摘要：
Using the principle of imaging interferometry we resolve structures with a relatively low NA microscope objective which could not be resolved in the conventional illumination setup. We show experimental results for the cases of 700-and 4000-nm period gratings. We compare these results with theoretical simulations and estimate the maximum resolution potential. Also we evaluate further advantages of our approach, such as field of view and working distance.
